I am trying to create a rdlc report for student marks, the report gives all the exam marks for a year I have grouped the rows as per studentId, column grouping is made on examinationId. Each exam has child exams, I am using subreporting to fetch the child exams and the parameters passed are academic year, class, subject and parent exam id. I am able to get the report but the subreport gives an error(failed to load subreport data). The expected report is as in the image, any suggestion how to achieve? Image shows expected report

It's going to be a bit tricky this one as we can't see the code and the error message is quite vague. I would suggest trying to split your problem up, comment/disable stuff and see if you can get something working.... Aside from that not too sure, – Richard Housham Mar 30 '20 at 14:25
